Zusammenfassung:	A motor drives a hub having axially extending blind tapered recesses to receive tapered shoes on a plurality of blades, and threads which fasten a ring that presses the shoes axially into the recesses have a hand-direction that tend to tighten in response to the rotation of the shaft. The recess is partially defined by a forward downward sloping upper wall. The shoe includes a forward downward upper surface. The recess sloping wall functions as a positive stop for seating the shoe by engaging the sloping shoe surface and as a centrifugal force absorbing wall during rotation of the blades.
